[Predictive capacity of anthropometric indeces in the detection of metabolic syndrome in Chilian adults]. / Capacidad predictiva de los índices antropométricos en la detecci6n de Sindrome Metabólico en adultos chilenos.

The presence of cardiometabolic components conditions the risk increase in the appearance of the metabolic syndrome and the associated pathologies. The insulin resistance is probably the subjacent mechanism to the complications derived from this syndrome, where the abdominal adipose accumulation is a common and f equent characteristic. The purpose of this study was to determine the predictive capability of the anthropometric estimating central adipose distribution indexes against the body mass index in the detection of the metabolic syndrome in Chilean adults. A descriptive crosssectional study was conducted on 229 adults, information obtained through a secondary database. There were analyzed through a Pearson correlation and receiver operating curves determining the area. under the curve. The results showed the predominance of 58.3% of the metabolic syndrome prevailed according to NCEP-ATP III, where the anthropometric indexes such as waist height index (0.746), waist circumference (0.735) and body mass index (0.722) didnot-show significant differences in the detection of the metabolic syndrome components. It did show a higher correlation of these cardiometabolic. factors with the waist height index and waist circumference.

Helicobacter pylori infection and gastrointestinal symptoms on Chilean pregnant women.

OBJECTIVE: the aim of this research was to determine the prevalence of Helicobacter pylori infection on Chilean pregnant women and its relationship with the appearance and severity of hyperemesis and dyspepsia. METHODS: quantitative study of prevalence in a transversal cut with variable analysis. The sample was taken from 274 Chilean pregnant women from the Bío Bío province through vein puncture between June and December, 2005. Pregnant women were informed of this study, interviewed and signed an informed consent. The samples were processed using ImmunoComb II Helicobacter pylori IgG kit. Statistical analysis was performed by means of the Statistical Package for Social Sciences (SPSS) Program. RESULTS: out of the total number of pregnant women, 68.6% showed infection by Helicobacter pylori. 79.6% of the total sample had symptoms of dyspepsia, and 72.5% of this group presented Helicobacter pylori infection. 12.4% showed pregnancy hyperemesis; among them, 79.4% were infected with Helicobacter pylori. 73.4% of the pregnant women that showed gastric discomfort during the first three months had Helicobacter pylori infection. 53.7% of them continued with gastric discomfort after the first three months; of those, 95.8% were infected. Helicobacter pylori infection was present only in 1.5% of pregnant women without gastric discomfort. CONCLUSION: both, gastric discomfort of pregnant women and the continuity of severe symptoms of dyspepsia and hyperemesis after the first three months of gestation are significantly correlated with Helicobacter pylori infection.

Objetivo: o objetivo desta investigação foi determinar a prevalência da infecção por Helicobacter pylori em mulheres grávidas chilenas e a sua relação com o aparecimento e agravamento de hiperêmese e dispepsia. Métodos: estudo de prevalência, quantitativo de coorte transversal com análise de variáveis. A amostra foi tomada através de punção venosa em 274 mulheres grávidas chilenas, da província de Bío Bío, nos meses de junho a dezembro de 2005. As mulheres que participaram foram informadas, assinaram um consentimento e responderam uma pesquisa. As amostras foram processadas usando o kit ImmunoComb II Helicobacter pylori IgG. A análise estatística foi realizada com o programa Statistical Package for Social Sciences (SPSS). Resultados: do total de mulheres pesquisadas, 68,5% apresentam infecção por Helicobacter pylori. Do total, 80,7% tiveram sinais de dispepsia; dessa porcentagem, 72,5% apresentaram infecção por Helicobacter pylori. Uma porcentagem de 12,6% das pacientes apresentou hiperêmese gravídica; dessas, 79,4% tiveram a infecção. Do total das mulheres grávidas com moléstias gástricas no primeiro trimestre de gravidez, 73,4% registraram infecção por Helicobacter pylori. Uma porcentagem de 53,7% continuou com moléstias gástricas depois do primeiro trimestre e dentro desse grupo 95,8% tiveram a infecção. Infecção por Helicobacter pylori estava presente em apenas em 1,5% das mulheres grávidas sem desconforto gástrico. Conclusão: as moléstias gástricas das mulheres grávidas e o agravamento dos sinais de dispepsia e hiperêmese depois do primeiro trimestre de gravidez estão correlacionados significativamente à infecção por Helicobacter pylori. .
